I was a horny young teenager! Margie was a neighbor, and a friend of my sister.
She was the older sister of the 11 year old neighbor girl . And two bros who were my friends.
I had been busy flashing the younger sister, Margie and my sister . I had masturbated for my sister twice . I had heard my sister talking on the phone . Yes !! It was a party line with other people on it . She was talking to Margie . They had set a time later for Margie to come over! Oh yeah !! I heard them say about 7. Margie came over . They both went up to my sisters room . About 20 minutes later . I thought why not !! I went upstairs. Went into my sisters room !
She told me to get out ! I said what ? You don’t want any fun? I just dropped my pants ! I had a hard on ! I grabbed it stroking it ! Both of them were looking . My sister said stop it !! I said ok just a minute! I grabbed some Kleenex off her dresser ! Squirted cum in my hand ! Said gee it looks like a nice load of cum ! I wiped off my hand put it in the trash basket right by Margie! I pulled up my pants facing Margie ! I said I hope you don’t mind a little entertaining. My sister got up and pushed me out of the door . I heard my sister ask Margie if she wanted to tell mom! Margie said no it was ok! Kinda fun watching your younger brother!
